Description

Technical Field

[0001] The present invention relates to the technical field of motor winding machines, and in particular to a wire embedding mechanism of a wire embedding and winding integrated machine. Background Art

[0002] The stator coil is one of the important components of the motor. There are many occasions where motors are used in industrial products. Many electrical products use it as a driving power source. The stator is the main component of the motor. The main component of the stator is the coil. The processing of the stator generally requires paper punching, winding, and embedding operations. Before embedding the wire, it is also necessary to cover the two ends of the stator with paper. At present, it mainly relies on automatic embedding and winding machines.

[0003] However, the current wire inserting and winding machines have the following problems: the current slot cover paper machines are generally set below the processing table, so the slot cover paper is pushed from the bottom up to print the paper, while for the wire inserting and winding machines, wire inserting, winding and paper printing are all carried out simultaneously. Since the driving mode of the copper pusher head and the push rod in the current wire inserting mechanism is a single-layer up and down drive, multiple copper pushers need to be set for stators of different specifications, and each copper pusher head is connected by a connector to achieve pulling, and the copper pusher head, push rod and guide bar are all fixedly connected to the pulling mechanism below. Therefore, the current wire inserting mechanism can only operate on the wire inserting of the same motor. If it is necessary to insert wires for different types of motors, the motor processing companies need to purchase wire inserting equipment separately, which undoubtedly increases the purchase cost of the equipment and has low processing efficiency. Summary of the invention

Then the fifth drive mechanism 9, the fourth drive mechanism 8 and the third drive mechanism 7 work to embed the wire and insert the wire on the wire cup station into the stator above. The working process of the fifth drive mechanism 9, the fourth drive mechanism 8 and the third drive mechanism 7 is as follows: the motor 2 131 drives the pulley 1 132 to rotate, and the belt drives the two pulleys 2 133 to rotate synchronously, and finally the two screw rods 134 rotate and finally drive the first push block 20 above to move upward to push the copper push rod 21 to move upward and insert it into the wire cup station.Ensure that the end of the push seat 25 above is inserted into the internal copper push head, drive the copper push head to push upward to insert the wire into the upper stator station, the motor three 121-1 works by driving the screw rod two 121 to rotate after being decelerated by the first reducer 121-2, so that the push block two 122 on the screw rod two 121 moves up and synchronously drives the push rod push tube 123 to move up, and finally realizes pushing the upper push rod to move up, the motor four 111-1 works by driving the screw rod three 111 to rotate after being decelerated by the second reducer 111-2, so that the push block three 112 on the screw rod three 111 moves up and synchronously drives the guide bar push tube 113 to move up, and finally realizes pushing the upper guide bar to move up, because the push rod push tube 123 is located in the middle layer, the copper push head push rod 21 is located in the innermost layer, and the guide bar push tube 113 is located in the outermost layer to form a three-layer structure, and there is no slot mechanism on the upper end of the push rod push tube 123 of the middle layer, and a large slot mechanism is provided on the guide bar push tube 113 of the outermost layer. The clamping head 26 is provided with a large clamping groove 27 for movably clamping the large clamping head 26 on the copper pusher rod 21, so the middle layer is relatively free to move. Moreover, for wire embedding, since the copper pusher and the pusher rod reach the top to realize the wire embedding process, the copper pusher and the pusher rod move up and down synchronously. Since the travel distance of the guide bar is the shortest, the copper pusher and the pusher rod finally rush to the top to realize the wire embedding process. At this time, the upper end of the pusher rod is located at the edge of the guide bar. Therefore, after the wire embedding is completed, when the copper pusher, the pusher rod and the guide bar are reset downward, since the top copper pusher moves downward, when the lower end surface of the movable clamping head 24 abuts against the large clamping head 26, the process of continuing to move downward will synchronously drive the pusher rod push cylinder 123 of the middle layer and the guide bar push cylinder 113 of the outermost layer to move downward and reset. Therefore, the universal wire embedding drive mechanism of this structure is used to realize the function of embedding wires for products in different wire cups, making the operation more flexible and convenient.

[0031] This structural setting achieves the following technical effects:

[0032] Since the copper pusher head, guide bar and push rod and the corresponding wire embedding driving mechanism in the existing wire embedding mechanism are installed in an integrated manner, that is, a stator of one specification needs to correspond to the same number of guide bars and push rods, and each guide bar and push rod needs to be fixedly connected to the wire embedding driving mechanism below through a connecting piece, resulting in that one wire embedding mechanism can only embed stators of the same specification. The present invention changes the above-mentioned existing wire embedding mechanism to place the copper pusher head 5-3 (the installation position of the copper pusher head belongs to the conventional technology), the guide bar 5-1 and the push rod 5-2 directly on the wire cup station to form a guide bar push rod assembly 5, and the wire embedding driving mechanism below adopts a separate three-layer driving mode to be constructed as a universal driving mode, that is, the first layer drives the copper pusher head (that is, driven by the fifth driving mechanism 9), the second layer drives the guide bar (that is, driven by the third driving mechanism 7), and the third layer drives the push rod (that is, driven by the fourth driving mechanism 8). , as long as one of the wire cup stations 4 on the station indexing turntable 3 corresponds to the stator station 2, it can ensure that the third driving mechanism 7, the fourth driving mechanism 8 and the fifth driving mechanism 9 below correspond to the guide bar, the push rod and the copper push head above. After the third driving mechanism 7, the fourth driving mechanism 8 and the fifth driving mechanism 9 are pushed up, they drive the corresponding guide bar, the push rod and the copper push head to move up and insert the wire in the wire cup into the stator of the stator station 2 located above, and finally realize the wire embedding operation. Therefore, this structural setting can realize that when any wire cup station on the station indexing turntable 3 rotates to reach the wire embedding station, the multi-layer and universal driving method of the present invention can be used to drive the wire embedding operation, further improving the versatility and also improving the working efficiency of the equipment; and the factory can purchase one equipment to complete the wire embedding processing of stators of various specifications, which undoubtedly reduces the purchase cost and processing cost of the equipment.
